Abstract

L'invention concerne un procédé de traitement d'image qui se rapporte au domaine du traitement d'informations. Le procédé comprend les étapes suivantes : un premier dispositif électronique reçoit une première entrée d'un utilisateur pour une première application; en réponse à la première entrée, le premier dispositif électronique acquière des premières données d'image; lorsque la première application n'est pas autorisée à accéder à des informations de confidentialité d'une image, le premier dispositif électronique supprime les informations de confidentialité dans les premières données d'image; et le premier dispositif électronique envoie les premières données d'image, après suppression des informations de confidentialité, à un second dispositif électronique au moyen de la première application. Ainsi, la suppression dynamique, lorsque les données d'image sont envoyées au moyen de l'application, des informations de confidentialité dans les données d'image sans données d'image originales stockées dans un téléphone mobile proprement dit sont modifiées, protégeant la vie privée de l'utilisateur.
